Dear Maintainer, light-locker fails to start. Trying to start it from a terminal produces: $ light-locker (light-locker:11648): dbind-WARNING **: 23:06:56.641: AT-SPI: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files ** (light-locker:11648): ERROR **: 23:06:56.642: session_id is not set, is /proc mounted with hidepid>0?

Thanks, Roger
Every time I start Plasma (also have xfce installed), it will give me an error that /usr/bin/light-locker has encountered a fatal error and was closed, I don't know what's happening or why it's trying to run when I start Plasma, but uninstalling it fixed it temporarily.
